How to enable Chaos

Thank you, it works !
Now it’s time to install everything

You need to have Visual Studio 2017 or 2019 installed. Grab some popcorn and watch a movie, it takes some time to install and compile everything

Just installed P5. The fracture editor does not appear. A little strange. Makes it hard to do Chaos.

I’m trying to just shoot a geocollection. But right now i can put it to sleep (if not, he was falling down), but i just can’t shoot it (projectile goes through. What i’m i missing
(i have the GitHub version)

Preview 5 has been released… Is Chaos now compiled in the launcher version, or we still need to download from Github?

anonymous_user_d0f8cc19 · August 8, 2019, 7:08pm

The GitHub link seems to be out? I cannot get to the repository.

Ga.rheault · August 8, 2019, 7:16pm

I’ve seen this video, but where can you find this blueprint, is there something else that i need to download?

Rainoxer · August 8, 2019, 7:32pm

Noone know how to make it, except the Epic employees…

anonymous_user_069ae814 · August 9, 2019, 11:16am

I had the same issue and ask for it a few answers before. You have to link your GitHub account to your UE4 account. And then, you’ll be granted the right to download UE4 projects on GitHub ;).
See @'s answer on page 8.
Go here to link accounts : Epic Games

Can Chaos work with Physics together? [TABLE]

		Why does my GeometryCollection Asset have no Collision?
		And they can't be Trace(Like use LineTraceByChannel)？
		Even my GeometryCollectionActor Blueprint asset's EventTick doesn't work/fire!!!
		Where can I get a demo for Chaos's using DETAIL？
		Thank you very much!!!

Wow what a pain in the ■■■ … well now it’s running.

This worked for me:

Get Unreal 4.23 P5 from github https://github.com/EpicGames/UnrealEngine/tree/4.23.0-preview-5 . Cloning it from the most recent commit can cause errors.
Set the line “bCompileChaos = true;” inside of the engine NOT inside the project!
Build the engine
Create a new project, set the version to 4.23 P5 and start the project
Enable the neccessary plugins and restart the project

Hello everyone,

Here is research I did to make the destruction “work” with chaos : (Caution! French explanation in coming.)

I’ve wached the video many times to figure out how works the field system => Fail, I still don’t know how it works.
Concerning the destruction :
| 2.1) The Geometry Collection works, you select a bunch of objects you want to gather and click on the “create” button located IN the chaos tab to create your Geometry Collection.
| 2.2) Tools to fracture seem to be “OK” and work.
| 2.3) I did not find a way to remove a depth of destruction or just to undo a destruction type (without CTRL+Z). Will it be added?
| 2.4) Contrary to the presentation video of the GDC, my geometry collection does not fall below the floor by remaining whole, it falls until it collides with the floor simulated by the ChaosSolverActor (an actor you’ll find in your world outliner when adding a geometry collection) and instantly destroys itself. If I change the height of the simulated floor of this actor, then my destructible object is going to be collided and destroyed at this height. The geometry collection does not interact with other types of object.
| 2.5) I succeeded in creating a floor and walls that collide with my destructible object. To do so, I created simple objects that I turned into geometry collection. These objects are set to STATIC. While my destructible object is DYNAMIC. (You find that setting on the General Tab in the Details of your Geometry Collection : “Object Type”.)
| 2.6) Using this technique, I tried to create a bullet to interact with my destructible object => Fail.
| 2.7) If you scale your Geometry Collection floor or your Geometry Collection walls, the chunks of your destructible object will not collide enterely with your floor and walls. That is to say, the destructible object will only interact with the original size of your floor and walls, even if they are scaled. So you can find flying chunks if you descrease the size of your static object by scaling or see chunks getting through if you increase the size of your static object by scaling.
| 2.8) My destructible object collapses instantly when I start my project, I haven’t found a way to leave it undestroyed and interact with it.
Collision betweens object : “Block All” doesn’t work (Or something is missing in my project). Every object I throw on my Geometry Collection goes through…

I hope these explanations will help. Feel free to ask questions if a point is unclear or if my English is approximate (Ahhh those French people !).

FYI, we’ll be doing a livestream on how to get started with Chaos on August 22nd. We’ll walk you through most of the questions that have been asked here, including fields!

VictorLerp · August 12, 2019, 5:41pm

You’ll have to compile the engine from GitHub to use Chaos until it’s out of Early Access, which will take a couple of engine versions.

I have P5 compiled and it runs great. I am creating Geo collections and they are OK. I just need some help from that point. A video would really help. I have a client ready for an app using Chaos. Noon’s video is great but not useful with P5. Help.

Can you shoot the GeoCollection and have it fracture?

That’s great news Really looking forward to it!

anonymous_user_fb040bbd · August 13, 2019, 1:41pm

I will be in the front row.

anonymous_user_f689bf281 · August 13, 2019, 7:03pm

Why I must build if by default it must be in UE4 editor?
